Control OptionsThis system is compatible with the optional MHK1 wireless, RFI-RedLINK™ enabled, full-function wall mount controller, allowing homeowners to control their unit from a remote PC, smartphone or tablet (sold separately). If you prefer a standard, fully wired and functioning wall mount control, this system also works with the PAR-31MAA (sold separately and requires control adaptor MAC-333IF).

Air FiltrationThese indoor units use a sophisticated multiple filtration system to ensure clean, healthy air throughout the rooms/zones they condition. The Hybrid Catechin washable pre-filter captures dust and eliminates odors, while the Blue Enzyme washable filter uses an enzyme catalyst to capture and eliminate allergens, germs, bacteria, and viruses.

Quiet OperationMr. Slim Indoor Units operate at very low sounds levels (19-35 decibels). According to a study performed by the National Institute for Occupational Safety and Health, most Mr. Slim Indoor Units are quieter than a human whisper (30 decibels) at low speed.

Environmentally FriendlyMitsubishi was clearly taking the environment into consideration when designing the M-Series line by using R410A refrigerant with zero Ozone Depletion Potential (ODP), 83% recyclable components, and washable filters made from natural materials on all models.

Haven't installed it yet but wanted to share how happy I was with Comfortup and with the shipper after reading reviews about negative experiences with other wholesalers not really having the products in stock and not being responsive in their handling of customer relations. I'll put another review of this product once I get it installed!
